Questions
Statement 1: The energy of charged particle moving in a uniform magnetic field does not change.
Statement 2: Work done by magnetic field on the charge is zero.
detailed solution
Correct option is A
The force on a charged particle moving in a uniform magnetic field always acts in direction perpendicular to the direction of motion of the charge. As work done by magnetic field on the charge is zero, W=FS cos θ, so the energy of the charged particle does not change.Talk to our academic expert!
